MarsProxies (marsproxies.com) offers four public product lines: rotating residential proxies billed per GB with never-expiring traffic, static ISP (static residential) IPs, static datacenter IPs, and dedicated mobile proxies on 5G/4G/3G networks.
Residential plans are prepaid GB packs from 1 GB ($4.99) up to 10 000 GB (about $1.65/GB). ISP and datacenter IPs are sold by quantity for 1, 30, or 90 days — for example 1 ISP IP at $2.99 for 30 days or 1 datacenter IP at $1.99 for 30 days; larger quantities lower the unit rate. Mobile proxies are priced per dedicated proxy for 1, 30, 60, or 90 days (from $8.49/day).
Buyer payments listed on product FAQs include Visa/Mastercard and other cards, PayPal, Google Pay, Alipay, and cryptocurrency. ISP and datacenter marketing copy claims unlimited bandwidth without a published fair-use threshold — treat that as unconfirmed for heavy use.
